It would be surprising to see the exact same fault in two radios, but I would also check pin 9 of the TA7222P speaker-amp chip. Should be close to one-half the DC voltage seen at pin 1, the chip's power-input pin.

Pin 9 is the next-to-rearmost pin. Pin 1 is at the end towards the front of the radio.
